.' SURGICAL SPLINT.

Be it known that I, CHRISTIAN H. Domino, a citizen of the United States," residing in Pottstown, Pennsylvania, have invented certain Improvements in Surgical Splints,, of

which the following is a specification.

. My invention relates 'tothat class of surgical splints which are used in connection with fractures of the forearm, and which have a hand grip at the forward end of the wrist portion of the splint, the object of the invention being to permit the use of the splint with equal comfort on either the right or the left arm.

In the accompanying drawingsFigure 1 is a face view of a splint constructed in accordance with my invention and having the hand grip adjusted as when the splint is used on the right arm; Fig. 2 is a similar view showing the hand grip adjusted as when the splint is used on the left arm; Fig. 3 is a side elevation of the splint shown in Fig. 2; Fig. 4 is a transverse section on the line aa, Fig. 2; and Fig. 5 is a view similar to Fig. 1 but illustrating a modification.

In the drawings, 1 represents the arm portion of the splint and 2 the wrist portion of the same, which are usually made of sheet metal and perforated as indicated, the arm portion being transversely bent or curved so as to partially envelopthat portion of the forearm to which it is applied.

The wrist portion 2 of the splint is provided with a hand grip 3, whose normal po-. sition is diagonal to the axial line of the splint, and in order that the splint may be used with equal facility on either arm I pivot this hand grip to the wrist portion of the splint so that it may be adjusted at one angle when the splint is to be applied to the right arm or at an opposite angle when the splint is to be applied to the left arm, the grip thus conforming to the natural and comfortable position-of the handin either case.

The hand grip is carried by a right angled plate 4, which is pivoted to the wrist portion of the splint, and I find it preferable to laterally shift the pivot point of the grip in changing the same from the right handposi-.

tion to the left hand position, for this reason the wrist portion of the splint is provided with two laterally separated openings 6 and 7 to either of which the pivot pin 5 can be applied. thus,'as shown in Fig.1 when the grip is adjusted for the right hand'the Specification o f'Letters i atent.

pin is appliedto the pivot opening on the left .of the center, andnwhen it;is;adjusted for the left hand position shown-in Fig. 2 it is the Opening on of. hecenten. i r g The pivot plate 4: of the grip is also provided with means for lockingthe same in position after the grip has assumed its proper angular relation to the wrist portion 2 of the splint. The locking means shown in Figs. 1

In order to provide for ready shifting of the pivot plate 4' of the grip from one to the other of the openings 6 and 7 the stem of the pin is preferably threaded for the reception of a nut 11 which bears upon the underside of the wrist portion 2 of the splint and can be readily removed when it is desired to shift the pin and asreadily applied in order to retain the pin in proper position after adustment. I Y f In effecting the shift the pin -5 is first re: moved, the plate 4 is then lifted so as to withdraw the pin 8 from the opening formerly occupied by it, and the plate is then shifted so as to readjust the grip 3 and applvthe pin 8 to the new opening in the splint, the pivot pin being then applied to its new opening and secured in position as before. I

As shown in Figs. 1, 2 and 4 the pin 8 is carried by the pivot plate 4 of the hand grip and the openings 9 andlO are formed in the wrist portion of the splint but it will beevident that the relation of the pin and openings may be reversed without affecting my invention. For instance, in Fig. 5 I have illustrated a splint in which a pin 8 occupies a fixed position on the wrist portion of the splint and the openings 9 and 10 for the reception of said pin are formed in the pivot plate 4, the openings 6 and 7 for the reception of the pivot pin 5 being also and 2 consist of a pin 8 which may engage formed in the pivot plate instead of in the Wrist portion of the splint, as in;,the,con-

' V plate ineither ofitsadjusted positionsysaid i Wrist portion of: the splint having a pluralof openings for the reception of pin and also a plurality of openings fomhe reception of the locking pin.

In testimony whereof," I' have signed my structions p 'eviously described.
